Wind tunnels are popularly used in testing of applications such as aerodynamics, automobiles, architects, submarine etc. A low speed wind tunnels and its type are present in this .This paper focuses on the wind tunnels and its computational solving approaches. Based on this study, the application of a wind tunnel leading to the quantative predictions have been a combination of theory and experiment. Low speed wind tunnels are about mach no =0.4, 134 m/s this paper gives the idea about various parameters and methods that used for calculation of pressure and temperature and computational methods. This review concludes that, the use of low speed wind tunnel can give the idea for improving the streamline shape of the model and by using scale model cost will be saved.
